The RaMbaM in his introduction to the More' explains why the Torah seems simplistic, because it speaks first to the masses and only hints for the greater scholar, because the point of Torah is people should do good actions.

Review of the ideas of צמצום and that it only relates to אור where the צמצום is שלא כפשוטו, but the מאור need not be מצומצם as it is a בלתי מציאות נמצא. At the same time the Alter Rebbe introduces us to the idea of המאור הוא בהתגלות which menas that the בלתי מציאות of מאור has a real effect on the creation.

Here we discover two levels in this non-revelation of revelation of המאור בהוא בהתגלות:

Revealing this (G-dliness in eating drinking etc.) isn't achieved by changing it (as we do when we do Mitzvos) but by thanking Him for it, then the "space" of the world is affected by the fact that he is fully revealed, as per המאור הוא בהתגלות.

This is also the ideas of כל מעשיך לשם שמים and בכל דרכיך דעיהו as explained in ושבתי בשלום ה'תשל"ח.
